In addition, a wearable device may include a body and a wearing part (astrap or band), and may be worn on various parts of a human bodyaccording to a configuration of the wearing part. The wearable devicemay be one of the following structures:

1. a structure in which the body and the wearing part are integrallyformed with each other and inseparable from each other;

2. a structure in which the body and the wearing part are separable fromeach other and thus are changeable.

Currently available wearable devices have several deficiencies. Forexample, the body of the wearable device is mostly designed regardlessof design aspects and the exterior of the body and the inner wearingpart are mostly formed according to the same flat/curved shape or abasic design shape.

Such a shape is not appropriate to the wearable device and acts as afactor delimiting functions and design of the wearable device.

In addition, where the wearable device has the body and the wearing partare integrally formed with each other, the body and the wearing part arenot changeable and thus there is a limitation to providing variousdesigns and customized functions. Furthermore, if the body and thewearing part are separable from each other and changeable, it would bepossible to customize the wearable device according to a user's taste inview of an exterior design or function. However, there is acontradiction between the degree of fastening and convenience inremoving the body, and deterioration of the wearing part caused by anindividual using pattern or frequent replacement may cause a seriousproblem in the fixing stability of the device.

The front surface 120 has a first curvatureand the rear surface 121 has a second curvature. The first and secondcurvatures may be determined to facilitate improved consumer wearabilityby having a shape or configuration to ergonomically correspond tovarious consumers' wrists. In the present embodiment, the firstcurvature is smaller than the second curvature. In other words, thefront surface 120 of the curved body 10 according to the presentembodiment has the display 11 mounted therein and thus should make iteasy for a user to view a displayed screen, and the rear surface 121should make the user feel good when the user wears the device on user'swrist, and has a sensor mounted thereon and thus should provide a shapeclosely contacting user's wrist.

The curved body 10 may be configured to gradually become thinner fromthe center toward the opposite sides thereof. The curved body 10 may berelatively thick on the center and may gradually become thinner towardthe sides. In addition, although the rear surface 121 has the secondcurvature in the above-described embodiment, the rear surface 121 may bea substantially flat surface without a curvature.

The exterior structure of the curved body 10 can ergonomically improve asensation that a user may feel when wearing the device and can improvecompatibility in response to various consumers' wrists. The curved body10 may be provided with the curved display 11 on the front surface 120and may include a skin contact surface provided with a sensor 13 (aninterface of the sensor is seen in FIG. 4) on the rear surface 121, sothat the degree of freedom of the exterior design can be maximized andoptimal sensor performance can be provided to all of the users. Inparticular, the rear surface 121 of the curved body 10, which is theskin contact surface, may be configured as a nearly flat surface incomparison to the free shape of the exterior design of the curved body10, and may have the sensor (s) arranged thereon to respond to all ofthe various body curvatures appropriately.

In addition, the curved body housing 12 in the present embodiment mayhave a sensor interface (SW) formed on the rear surface thereof which isin close contact with user's skin, and has the display, a touch inputpart, a button key, a charging terminal, and an information interfaceformed on a surface other than the skin contact surface (bottom surfaceof the body housing).

The display 11 is formed in a shape reflecting a curved shape of thehuman body and may be formed in a flat shape (Liquid Crystal Display(LCD), Organic Light Emitting Diode (OLED)) or a curved shape (flexibleOLED). Although the display 11 is provided in the present embodiment isdescribed as being curved, the display 11 may instead be configured as aflat display.

A seating recess 13 may be formed on the side surface of the curved bodyhousing 12. The seating recess 13 extends along the side surface 122 ofthe curved body housing 12. An exterior side surface of the sidesurfaces of the curved body housing 12 that is seen by the user has acurvature. The seating recess 13 has the same curvature as the firstcurvature of the front surface 120 of the curved body housing 12.However, the curvature of the seating recess 13 may be the same as thefirst curvature, but may be larger or smaller than the first curvaturesince men and woman have various wrist curvatures. In FIG. 6, thecurvature of the seating recess 13 is the same as the first curvature.As will be described, the seating recess 13 includes a top surfacecurvature and a bottom surface curvature in some section. The bottomsurface curvature may vary to respond to various wrist curvatures. Thetop surface curvature and the bottom surface curvature of the seatingrecess 13 may vary in a boundary area with the body according to a wristcurvature of a user who wears the wearable device.

In the above-described embodiment, the seating recess 13 has acurvature, and a top surface 33 a and a bottom surface 33 b of theseating recess 13 have the same curvature. The seating recess 13 formedon the outside surface of the body housing 12 may extend to have thecurvature with the same width and the same thickness and thus the topsurface 33 a and the bottom surface 33 b of the seating recess 13 havethe same curvature as the first curvature.

FIG. 7 is a section view showing arrangement of electronic partsprovided in the curved body 10 according to various embodiments of thepresent disclosure. FIG. 8 is a side view showing the curved body 10according to various embodiments of the present disclosure. FIG. 9 is aside view showing arrangement of substrates and electronic partsprovided in the curved body 10 according to various embodiments of thepresent disclosure.

Arrangement of electronic parts mounted in the curved body 10 will beexplained with reference to FIGS. 7 to 9. In the present embodiment, acurved battery 14 is mounted under the display 11 in a layeredstructure, such that the curved body 10 gradually becomes thinner fromthe center toward the opposite sides. That is, the curved body 10 hasthe curved display 11, the curved battery 14, and substrates P1-P3layered therein one on another.

In the present embodiment, the curved body 10 may be configured suchthat an exterior surface which is easily seen with user's eyes (forexample, a display screen) and a contact surface which is worn on ahuman body and is in close contact with a skin (a rear surface of thebody housing) have different curvatures, and has an optimum layeredstructure of electronic parts mounted therein. The curved body 10according to the present embodiment is provided with the display 11having the highest degree of freedom of manufacturing a curved surfaceon the exterior surface having the largest curvature, and has thebattery 14 installed inside the display 11. In this case, the battery 14has a curved shape and has the same curvature as the first curvature.The battery 14 may be mounted with reference to the center of the curveddisplay 11, and facilitates providing or guaranteeing mounting spacesthat are formed at both ends of the battery. The mounting spaces may beused as spaces for compensating for reduction in the curvature of theskin contact surface (rear surface). The above-described mountingstructure results in reduction in the thickness at the both ends incomparison to the center of the curved body 10, thereby achieving a gooddesign and minimizing a step height which may be generated with respectto the wearing part 20.

Hereinafter, the arrangement of various electronic parts and substratesmounted in the curved body 10 will be explained.

The curved battery 14, a plurality of electronic parts s, m, and c and aplurality of substrates P1, P2, and P3 are arranged in the curved body10. The curved display 11, the curved battery 14, and the plurality ofsubstrates P1, P2, and P3 are arranged in the curved body 10 in avertically layered structure. In particular, the battery 14 according tothe present embodiment is disposed on an intermediate layer between thecurved display 11 and the substrate P1. This structure is to serve as asafety device for preventing a low temperature burn caused by heatemitted from the battery and minimizing any damage to the user caused byexplosion of the battery, and may be a vertically layered structure.

The curved body 10 includes the curved body housing 12 and an innerbracket 15. The curved body 10 forms a single body by coupling the innerbracket 15 to the curved body housing 12. The body housing 12 and theinner bracket 15 may be independently manufactured and coupled to eachother. However, the inner bracket 15 may be included in the body housing12. The curved display 11 may be attached to the front surface of thebody housing 12 by an adhesive tape (double-sided waterproof tape), andthe inner bracket 15 may be received in and fixed to the body housing12. The inner bracket 15 may receive the curved battery which is layeredunder the curved display 11 and one or the plurality of substrates P1,P2, and P4 arranged between the front surface 120 and the rear surface121 of the body housing 12.

In addition, according to the present embodiment, the plurality ofsubstrates P1, P2, and P4 may be arranged in the inner space of the bodyhousing 12, specifically, in the inner bracket 15. In this case, asegmental (articular) structure substrate may be applied, therebyimproving efficiency of mounting of the electronic parts. Theabove-mentioned segmental structure substrate appropriately providesrigid substrates P1, P2, and P3 and flexible substrates F1 and F2 tosections where the substrates are needed, thereby smoothly implementinga curved design, and may have the electronic parts directly arranged inrespective segmental sections separately according to a requiredcondition, thereby improving performance of the electronic device. Forexample, a part vulnerable to a noise and a noise generating part may bearranged on separate substrates and a part vulnerable to a shock and ashock generating part may be arranged on separate substrates. Sucharrangement of the electronic parts may naturally separate a noisegenerating section and a noise sensitive section from each other and mayblock a vibration shock transmitted through the rigid substrates P1, P2,and P3 in the section of the flexible substrates F1 and F2, therebyachieving a design for optimizing electrical performance of theelectronic device and durability. In the future, a curved rigid orflexible substrate will be applicable instead of the above-describedrigid substrate thanks to the technology development. In theabove-described substrate segmental structure, a non-contact sensor suchas a gyro sensor, an acceleration sensor, and/or other optical sensorsmay be further provided in addition to the basic parts related tocommunication or input and output.

The plurality of substrates may include the plurality of rigidsubstrates (for example, Printed Circuit Boards (PCBs)) and theplurality of flexible substrates (PCBs), and the rigid substrates P1,P2, and P3 are substrates where various electronic parts are mounted andthe electronic parts may be mounted on both the top surface and thebottom surface of each of the rigid substrates P1, P2, and P3. In FIG.7, three rigid substrates are mounted and are referred to as a firstsubstrate P1, a second substrate P2, and a third substrate P3. The firstsubstrate P1 is disposed in the center, the second substrate P2 isdisposed on the right of the first substrate P1, and the third substrateP3 is disposed on the left of the first substrate P1. A substrateconnecting the first substrate P1 and the second substrate P2 isreferred to as a first flexible substrate F1, and a substrate connectingthe first substrate P1 and the third substrate P3 is referred to as asecond flexible substrate F2. The first, second, and third substratesP1, P2, and P3 and the first and second flexible substrates F1 and F2are connected with one another, thereby configuring the segmentalsubstrate.

In addition, when various electronic parts are arranged on the first,second, and third substrates P1, P2, and P3, parts vulnerable to a noiseand noise generating parts may be arranged on separate substrates, andparts vulnerable to a shock and shock generating parts may be arrangedon separate substrates.

For example, out of the electronic parts mounted on the substrates, apart vulnerable to a noise (PAM) and a noise generating part (AP, CP)may be separately arranged on the first and second rigid substrates P1and P2, respectively, and a part vulnerable to a shock (a BGA part suchas AP and CP) and a shock generating part (for example, a vibrator or avibration motor) may be separately mounted on the second and thirdsubstrates P2 and P3, respectively. Such inner arrangement of theelectronic parts can naturally separate a noise generating section and anoise sensitive section from each other, and block a vibration shocktransmitted through the rigid substrates in the flexible substratesection, thereby achieving a design for optimizing electricalperformance of the electronic device and durability.

In addition, at least one of the rigid substrates disposed on the rearsurface 121 of the body housing 12 may be horizontally placed or may beslantingly placed. The first substrate P1 is disposed in the center andhas a first sensor (s) (which is exposed from the rear surface of thebody housing and is in close contact with a skin of a human body toacquire a variety of information on the human body) disposed thereon.Therefore, the first substrate P1 should be placed horizontally alongwith the first sensor (s). The first sensor (s) may be exposed from therear surface of the body housing and may be disposed on a location wherethe first sensor (s) is in the closest contact with the skin. That is,the first sensor (s) may be horizontally disposed substantially on thecenter of the rear surface 121 of the body housing. The first sensor (s)may be mounted on the rear surface of the first substrate P1 and asensor interface (sensor interface window) may further be provided. Inaddition, even when a PCB is mounted slantingly with respect to theexterior surface of the housing, a balance can be maintained by using aninterposer between the PCB and the first sensor. The first sensor (s)may have the sensor interface window exposed from the rear surface 121of the body and may be horizontally disposed. The sensor interfacewindow may be provided on the sensor or may be attached to the exteriorof the body housing. For example, the first sensor (s) may be a HeartRate Monitor (HRM) or a vein sensor which can acquire information fromuser's skin or body.

Additionally, the first sensor (s) which is exposed from the rearsurface 121 of the body housing may further include a protrusion 125protruding toward the rear surface, while enclosing the circumference ofthe first sensor (s) with a predetermined thickness. The protrusion 125may make the sensor interface, for example, the sensor interface window(SW), exposed and more brought into close contact with the skin. Thesensor interface (SW) is located on a flat surface of the rear surface121 and the flat surface is located on the center.

In the present embodiment, even when the segmental structure substratesare used, at least a horizontal and flat part seating plane part (anarea where the first substrate is mounted in the body housing) should beprovided to mount electronic parts, and the plane part requires a planeseating structure for performing a function such as a function of asensor. In the present embodiment, when a space guaranteed at the bothends of the curved battery 14 is used as a mounting area, a loss in themounting space caused by the substrate being mounted on the plane can beoffset. In particular, when a relatively thick part such as a vibrator(m) or a connector is placed, an inevitable increase in the totalthickness of the curved body can be prevented. Although not shown,various mechanism configurations such as a sub battery or a hookassembly can be mounted in the guaranteed space.

In the curved body 10 according to the present embodiment, the thirdsubstrate P3 is disposed between the lower side of the display 11 andone side area of the battery 14 (Y-axis direction), and the motor (m) isdisposed on the third substrate P3 and the charging terminal (c) isdisposed on the first substrate P1. The motor (m) is horizontallydisposed in parallel with the battery 14 and the charging terminal (c)is horizontally disposed in parallel with the battery 14. The motor (m)is disposed on the top surface of the third substrate P3 and thecharging terminal (c) is disposed on the bottom surface of the firstsubstrate P1. The charging terminal (c) is exposed from the rear surface121 of the body housing. Since the motor (m) is a relatively thick partor a part of a great volume, it is advantageous to dispose the motor (m)on the second substrate P2 or the third substrate P3 in view of theefficiency of mounting.

As other input devices mounted in the substrates, an electric switchinterface using a touch sensor, a pressure sensor, a temperature sensor,and the like, and a physical switch interface such as a tact dome keymay be disposed on one surface of the body housing, on which the usercan manipulate. Charging and interface terminals may further be disposedon a location of the front surface or the rear surface of the bodyhousing that does not deface the exterior. In the present embodiment,the charging terminal (c) is disposed on the rear surface 121 of thebody housing. According to the present embodiment, the surface that doesnot deface the exterior of the wearable device may be the rear surfaceof the body housing, that is, the surface which is in contact with thehuman body.

Hereinafter, the configuration of the display 11 disposed on the frontsurface of the curved body 10 will be explained.

FIG. 10 is an exploded perspective view showing the configuration of thecurved display 11 provided in the curved body according to variousembodiments. Referring to FIG. 10, the display 11 applies a flexible LCD110 having a curvature and a curved window 112 having the same curvatureas that of the flexible LCD 110 to achieve a curved design having acurvature. The curved window 112 includes a rigid or flexible layer.

The display 11 has a shape reflecting a curved part of a human body andmay include a curved LCD (flexible OLED). The design of the frontsurface of the body can be achieved by the curved surface of the LCD orthe curved window 112 presenting a curved surface. The display 111 mayfurther include a sensor for detecting a touch, pressure, or temperaturein addition to the curved flexible LCD 110, thereby providing aPerceptual User Interface (PUI) optimized to use of various userinterface (UIs). In addition, the window 112 ma provide a layer made ofa ceramic material such as glass and a sheet material such as PET, PC,and the like to protect the surface.

FIG. 11 is a perspective view showing the curved battery 14 provided inthe curved body according to various embodiments of the presentdisclosure. Referring to FIG. 11, the battery 14 according to anembodiment of the present disclosure applies a curved battery pack,thereby improving efficiency of mounting of the electronic parts in thebody. The curved battery 14 may be mounted in a bent state. This is afactor that is optimized to realize the exterior design of the curvedbody and mount an HW part of the wearable electronic device worn on thehuman body.

The battery 14 may be manufactured in a bent shape and configured tohave a predetermined curvature. The front surface and the rear surfaceof the battery 14 each have a curvature. The curvature of the battery 14may be the same as the curvature of the display and thus the battery 14may be disposed to face the rear surface of the display. A mountingspace may be formed on the center of the rear surface of the battery 14and can be utilized effectively by mounting a hardware electronic parttherein. The battery 14 may not have the same curvature as that of thedisplay. In addition, although the battery 14 may be disposed betweenthe display and the substrate, the battery 14 may be configured in aflat shape and may be disposed on the bottom surface of the substrate.

Referring back to FIG. 7, a separate layer part 142 may be added betweenthe curved battery 14 and the first substrate P1 to prevent breakage ofparts of the first substrate P1 and the battery caused by volumeexpansion of the curved battery 14. The layer part 142 stops volumeexpansion of the battery 14. The layer part 142 may act as a physicalsupport structure or a buffering section for the curved battery 14 andthe first substrate P1, and may be provided in the form of a barrier forpreventing a battery liquid from leaking to the lower side. The layerpart 142 may be provided as a conductive or metal piece or an injectionmolding piece.

FIG. 12 is a plan view showing the front surface 120 of the body housingaccording to an embodiment of the present disclosure. In the presentembodiment, an assembly structure of the body housing 12 without a screwboss is provided. The inner bracket in which electronic parts aremodularized and the body housing 12 may be fixed by a hook and thedisplay window and the front surface 120 of the body housing may beassembled with each other by using a waterproof tape. Therefore, theinner mounting space can be maximized and the waterproof function can bemaximized by excluding a screw boss. Reference numeral 120 a indicates asurface to which the waterproof tape is attached.

FIG. 13 is a partial cutaway perspective view showing the curved bodyprior to being mounted on the wearing part according to variousembodiments of the present disclosure. Referring to FIG. 13, a bodyremovable structure provided in the wearable device according to anembodiment of the present disclosure and a direction of removal will beexplained. In the present embodiment, an undue bending operation mayoccur between the body 10 and the seating part 22 due to a shapecharacteristic of the bar type body 10 having a curvature and variouscharacteristics of body shape of the user. In this case, a structure maybe configured to provide a removal force according to a direction of thepresent embodiment needs to fix the longitudinal end of the body 10 moretightly. The size of the seating part is designed to be smaller than thelongitudinal size of the body so that the side surface of the body canbe hold relatively stronger by elasticity of the wearing part. Inaddition, a separate bending prevention protrusion structure may beadded to a certain section of the seating part facing the body withrespect to the section where an undue bending operation occurs when thewearable device is worn on the human body.

Referring to FIG. 13, the body 10, that is, the body housing 12, may beremovable from the wearing part 20. The direction of removal may includea coupling direction (that is the relative direction that the bodyhousing 12 and the wearing part 20 move to effect coupling) in which thebody 10 moves from bottom to top and is coupled to the seating part 22,and a decoupling direction (that is the relative direction that the bodyhousing 12 and the wearing part 20 move to effect decoupling) in whichthe body 10 is pushed down and is decoupled from the wearing part 20.The coupling direction refers to a direction in which the body coupledto the wearing part 20 is prevented or inhibited from being separatedfrom the human body.

The curved body housing 12 may have a widthwise direction in which thewidth is gradually reduced from the rear surface or the center to thefront surface, such that removal of the body housing 12 from the wearingpart 20 may be accomplished by moving the body housing 12 and thewearing part 20 apart from each other in a first direction but not in asecond direction that is opposite that of the first direction, therebyproviding a first removal direction. The width W2 of the body housing 12on the front surface in the widthwise direction (X-axis direction) issmaller than the width W1 on the center (including the rear surface) inthe widthwise direction. The body housing 12 having the above-describedshape should be moved from bottom to top with reference to the seatingpart to be coupled to the seating part. The side surface of the bodyhousing includes a first part enclosing between the recess 13 and thefront surface 120 and a second part enclosing a part between the recess13 and the rear surface 121, and the width W2 of the first part is setto be smaller than the width W1 of the second part when viewed in across section of the body housing 12 cut perpendicularly to the firstdirection (Y-axis direction). The above-described structure provides thefirst removal direction.

In addition, the removal structure for coupling or decoupling the curvedbody housing 10 to or from the seating part 22 may be formed along thecircumference of the opening provides a second direction of removal. Theremoval structure includes the seating recess 13 and the seating part22. The seating recess 13 may extend along the circumference of the sidesurface 122 of the curved body housing and continuously extends with thesame curvature as the first curvature. The seating part 22 may betightly coupled to the seating recess 13 to fix the curved body housing10 to the opening 21. The seating part 22 may be made of an elasticmaterial and is elastically deformable according to whether the seatingpart 22 is coupled to the seating recess 13 or not, and the opening ofthe seating part is configured to be slightly smaller than the curvedbody housing so that the seating part is tightly coupled to the seatingrecess 13. In particular, the seating part 22 may be coupled to theseating recess formed along the outer circumference of the side surfaceof the side surfaces 122 of the curved body housing to have the samecurvature as the first curvature.

The seating recess 13 may be provided with a first close contact surfaceincluding a first top surface 130, a first intermediate surface 131, anda first bottom surface 132. The seating recess 13 may be configured tohave the horizontal width of the exterior corresponding to the firstbottom surface 132 wider than the horizontal width of the exteriorcorresponding to the first top surface 130. The first top surface 130may be configured to be horizontally flat or substantially horizontallyflat, and the first bottom surface 132 may be configured to behorizontally flat or substantially horizontally flat.

In addition, the seating part 22 includes a second close contact surfaceincluding a second top surface 220, a second intermediate surface 221,and a second bottom surface 222 and which is in close contact with thefirst close contact surface. The second top surface 220 may beconfigured to be horizontally flat or substantially horizontally flatand the second bottom surface 222 may be configured to be horizontallyflat or substantially horizontally flat. The seating part 22 isconfigured to have the horizontal width of the exterior corresponding tothe second bottom surface 222 wider than the horizontal width of theexterior corresponding to the first top surface 220 such that removalmay in accomplished by moving the body 10 relative to the seating part22 in one direction but is inhibited in the opposite direction, therebyproviding the second removal direction.

The second close contact surface of the seating part 22 is formed in ashape corresponding to the first close contact surface of the seatingrecess 13, so that the body can be safely coupled to the wearing partand safely decoupled from the wearing part when necessary. Such aremoval structure can prevent unexpected removal caused by a wearingpressure when the user does physical activity (can prevent the body frombeing decoupled from the wearing part).

Hereinafter, a waterproof structure of a wearable device according to anembodiment of the present disclosure will be explained with reference toFIGS. 14 to 16. FIG. 14 is a partial cutaway perspective view showing awaterproof structure applied to a plurality of parts of the wearabledevice according to various embodiments of the present disclosure. FIG.15 is a partial cutaway perspective view showing a waterproof structureapplied to a side key of the wearable device according to variousembodiments of the present disclosure. FIG. 16 is a partial cutawayperspective view showing a waterproof structure applied to a chargingterminal of the wearable device according to various embodiments of thepresent disclosure. As shown in FIGS. 14 to 16, the wearable deviceaccording to the present embodiments applies a uni body structure bycoupling the body housing and the battery bracket, thereby minimizingthe number of waterproof points. The wearable device according to thepresent embodiments includes a plurality of waterproof structures. Thewaterproof structure of the wearable device according to the presentembodiments is applied to a place where the curved window 112 isdisposed, a place where the side key (k) is disposed, a place where thesensor (s) is disposed, and a place where the charging terminal (c) isdisposed.

First, the waterproof structure for the curved window 112 mounted on thefront surface 120 of the body housing applies a waterproof tape (T1).The curved window 112 is attached to an adhesive surface of thecircumference of the front surface 120 to which the waterproof tape T isattached by using the waterproof tape T1. The waterproof tape T1 is adouble-sided tape and has an upper surface attached to the curved window112 and a lower surface attached to the adhesive surface 120 a of thefront surface (shown in FIG. 12). Water is prevented from entering thebody housing 12 by the waterproof tape T1.

Secondly, the waterproof structure for the side key (k) disposed on theside surface 122 of the body housing applies a waterproof tape T2. Thewaterproof tape T2 may be a double-sided tape and may be provided toenclose the side key (k). One surface of the waterproof tape T2 may beattached to the inner surface of the body housing where the side key isdisposed, and the other surface is attached to a silicon rubber, so thatwater is prevented or inhibited from entering by the waterproof tape T2.In addition, the side key (k) includes a silicon rubber for providing arestoring force when it is pressed, and a waterproof protrusion P istightly arranged along the circumference of the silicon rubber (see FIG.15) so that water is prevented from entering between the silicon rubberand the inner surface of the body housing. The silicon rubber preventswater from entering through the lower side by using the waterproofprotrusion P and prevents water from entering the upper side by usingthe waterproof tape T2 placed on the lower side.

Thirdly, a waterproof structure using a waterproof tape T3 is applied tothe sensor (s) disposed on the rear surface 121 of the body housing. Thesensor (s) is provided with a sensor interface (sensor window) and thewaterproof tape T3 is a double-sided tape and has one surface attachedto the inner surface of the body housing and the other surface attachedto the bottom surface of the sensor interface (sw). The waterproof tapeT3 is attached along the lower circumference of the sensor interface(sw).

Fourthly, a waterproof structure is applied to the charging terminal (c)disposed on the rear surface 121 of the body housing. The waterproofstructure for the charging terminal (c) may be achieved by fitting ahigh elastic waterproof part R made of rubber or silicon material intothe charging terminal (c). The waterproof part R is disposed between theside surface of the charging terminal and the inner wall of the bodyhousing to prevent water from entering the charging terminal. Inaddition, a waterproof tape P4 is attached between the body of thecharging terminal and the inner surface of the body housing to preventwater from entering the body of the charging terminal (c). In additionto the waterproof tape, various kinds of adhesive such as a bond,silicon, and the like may be used as a waterproof member.

FIG. 17A and FIG. 17B is a section view showing a boundary area Abetween the body and the wearing part according to various embodimentsof the present disclosure. Referring to FIG. 17A and FIG. 17B, theconfiguration of the wearing part according to various embodiments ofthe present disclosure will be explained. The wearing part 20 includes aseating part and a band. When a user wears the wearable device on user'swrist, the wearing part 20 is subject to a pulling force in the boundaryarea A between the body 10 and the wearing part 20. In this state, theremay be a gap between the body 10 and the wearing part 20 (the pullingforce is concentrated) and the gap may deface the exterior. To preventthis problem, a coring section in the form of a cavity is provided onthe inner surface of the end of the wearing part 20 in the boundaryarea, that is, on a certain section of a wearing surface. The end of thewearing surface is relatively thinner than the other parts by the coringsection. Therefore, when the user wears the wearable device on theuser's wrist, the wearing part, which is relatively thin, may berelatively more bent such that a gap is inhibited or prevented frombeing generated between the body 10 and the wearing part 20.

FIG. 18 is a view showing an example of an assembly order of thewearable device according to various embodiments of the presentdisclosure. An assembly process of the wearable device according to thepresent embodiment will be explained with reference to FIG. 18.Referring to FIG. 18, a battery bracket (inner bracket) for fixingelectronic parts is further provided in the present embodiment. Astructure by coupling the body housing and the battery bracket to eachother is to guarantee assembly of a uni-body housing structure optimizedto waterproofing. In addition, various electronic parts may be fixed tothe battery bracket by assembling, attaching, fusing, riveting,screwing, and the like. The present embodiment may provide an assemblystructure that excludes a screw boss. The battery bracket in which theelectronic parts are modularized and the body housing are fixed by ahook and a gap between the curved window and the body housing isfinished by a waterproof tape, so that the inner mounting space can bemaximized and the waterproof performance can be maximized by excluding ascrew boss. First, the battery is mounted in the battery bracket and aconductive or metal piece is fixed to the center of the rear surface ofthe battery. Next, a substrate assembly is assembled with the batterybracket and the display is fixed to the battery bracket. Finally, thebody housing is assembled with the battery bracket assembly and a finalassembly is completed.

FIG. 19 is a side view showing a wearable device according to variousembodiments of the present disclosure, in which a body 30 and a wearingpart 40 is decoupled from each other. FIG. 20 is a side view showing thebody 30 and the wearing part 40 which are coupled to each otheraccording to various embodiments of the present disclosure. Inexplaining the configuration of the wearable device according to thepresent embodiment with reference to FIGS. 19 and 20, redundantexplanation of the same elements as those of FIGS. 2 and 3 will beomitted and only differences will be explained.

In general, users' wrists have different curvatures when users wearwearable devices on their wrists. Since the respective curvatures of theusers' wrists are different, a wearing sensation that each user can feelmay be different. In particular, since woman's wrist is thinner thanman's wrist, the wearable device cannot fit all of the users. However,since the wearable device according to the present embodiments has astructure in which the wearing part 40 is removable from the body 30 andthe wearing part is changeable, users can select the wearing part to fittheir respective body sizes.

The wearing part 40 of the wearable device according to the presentembodiment of FIGS. 19 and 20 has a different curvature from the wristcurvature provided by the wearing part of the wearable device shown inFIGS. 2 and 3.
